JOURNAL-BEARING SHELL.

SPECIFICATION formingpart of Letters Patent No. 722,327, dated March 10, 1903.

Application filed. June 30, 1902- Serial No. 113,728. (No model.)

To all whom it may concern:

Be it known that I, MosEs J. ROGERS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of 5 Missouri, have invented new and useful Iniprovements in Journal Bearing Shells, of which the following is a specification.

My invention relates to car-journal bearings; and the object of myinvention is to pro- ;0 vide a bearing brass or shell having internal ribs for holding the Babbitt metal in position in addition to the usual dovetail grooves in the sides of the brass. The Babbitt metal cannot possibly come loose from a shell constructed in accordance with my invention.

Referring to the accompanying drawings, Figure 1 is an inside or bottom plan view of a bearing-shell embodying my invention. Fig. 2 is a transverse section taken on line II II. Fig. 3 is a longitudinal section taken on line III III, showing also the Babbitt metal in position. Fig. 4 is a broken-away section of one of the ribs, taken on line IV IV. Fig. 5 is an end elevation of the half of the bearing shown in Fig. 3.

1 is the shell, which is cast in the usual external form. On the inner side or crown are two integral ribs 3 and 3, which intersect each other, as shown, and extend diagonally the length of the shell. A transverse section of either of these ribs is dovetail in shape, as shown in Fig. 4. Across the ends of the shell are two internal transverse ribs 4 and 4, in-

tegral with the ends of the diagonal ribs 3.

The inner faces of all the ribs 3 and 4. are concaved to fit a cylinder of the same diameter as that of the axle-journal, so that if the Babbitt metal 6 should melt (which occasionally occurs) the faces of said ribs would sink down upon the journal and would provide an adequate bearing-surface until a new bearing could be substituted. Along each inner side of the shell are two integral sharp-edged ribs 7 and 7, which retain the edges of the Babbitt metal 6 firmly in the shell, so that it is impossible for the Babbitt metal to become loosened or detached from the shell except by
